Hello,

As all the components are new and you do not have any leak then really bleeding the brake is the only thing left to do.
Keep in mind that ABS system bleeding requires certain steps for it to be effective.

Here is a helpful guide to brake bleeding:

I have attached the ABS bleeding procedure below.

Please let me know of any questions.
Thank you.
